T 0 all whom t 'may concern Be it known that li, RICHARD H. MARVIN, a citizen of the United States of America, and residing at East Liverpool, in the county of Columbiana and State of Ohio, have invented certain new and useful improvements in Insulator Connectors, of which the following is a specification.

My invention relates to insulator connectors, the object of my invention being to provide a simple device for securing together the links by which insulators of the suspension type are connected together.

ln the accompanying drawingslFig. 1 is a vertical section through adja cent units of a suspension insulator showing a link connection in which my invention is embodied Fig. 2 is a perspective of the connector alone; and

Fig. 3 is a side elevation thereof.

The particular construction of the insulator does not enter into my invention, and lf. have illustrated the well known disc type 5, the body of which pierced by passages (S and 7 lying in planes right angles to each other, and through which are passed flexible metal links El and n", by which the units are connected. A pair of separate links, one for each insulator unit are here used, but obviously a single link of greater length engaging both insulators could be substituted if preferred. The links are provided with enlarged heads 9 adapted to engage the connector l0, to which my invention particularly relates. As here shown the link heads 9 are circular and the connector 10 is cylin drical, although the particular shape of the heads and connector may be varied if desii-ed.

The connectorv 10 comprises a tubular body closed at its opposite ends 11 und 12 to form seats for the heads of the links, but slotted at 13 and 1li to accommodate the shanks of the links. A lateral entry opening 15 is formed in one side of the connector to admit the heads 9 to the interior thereof, while the end slots are extended through the side Walls at 16 and 1? into communication with the opening 15 to permit the shanks of the link to pass therethrough into the slots and la on the assembly o the parts. rlhe opening 15 is preferably of such dimensions that it will permit but one of the link heads 9 to pass therethrough, it being necessary to draw the head first inserted down against the end 11 or 12 of the connector before the other head is passed through the opening 15. This construction minimizes the danger of escape of the heads from the connector should the links become slack.

In order to further reduce the risk of escape of the heads 9 from the connector l may provide a Cotter 18 adapted to be passed through the hole 19 in the wall of the con nector opposite the entry opening 15. rllhis cotter serves as a retainer and as a filler piece, which prevents the approach of the heads 9 of the links sufficiently close together to enable either to pass through the door 15 after the parts are assembled. Any other suitable i'iller or obstruction means may be used to prevent the escape of the heads 9 from the connector, or such means may be entirely omitted since the danger of escape from the connector extremely remote.

lhe present device is siu'xple to manufacture, readily installed, and etiicient in operation. l do not limit my invention to the precise defails shown, which may be variously modified Without depart-ing from what l claim as my invention.

l claimin insulator link connector comprising a flat-ended hollow cylindrical member, the walls of which are of substantially uniform thickness at all points, the side wall and opposite ends of said member being slotted to receive the Shanks of associated link elements, said slot in the side wall of said member being notched to form a bay through which the heads of said link elements may be introduced. into and seated in the wells afforded by opposite ends of said hollow member, the side wall of said meinber being apertured at a point opposite said bay to accommodate a filler elements introduced therethrough between the link heads to prevent their accidental escape through the bay.

ln testimony whereof have signed my name te this specification. i
